SA-ISAR imaging algorithm based on the gradient signal recovery method
The Journal of Engineering, 2019 As the radar system tends to be complex, obtaining well-focused images with discontinued apertures becomes a challenge. Here, a new sparse aperture inverse synthetic aperture radar (SA-ISAR) imaging approach through the signal recovery method is proposed.

Long-Time Observation-Based Multiattitude ISAR Imaging Method for Moving Ships
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingLong-time synthetic aperture radar observation facilitates the tracking and identification of moving targets. However, continuous changes in the attitude of a moving target during long-duration observations cause the azimuth signal’s time– ...
